How Might a Scientist Investigate Annual Patterns of Fires?
ES0201  Wind Speeds

Wind brings a constant supply of fresh oxygen to an area, and oxygen is necessary for burning. Wind can also carry sparks from contained fires to other areas. Fires are less likely to start in calm winds.

USDA Forest Service, Wildland Fire Assessment System

Examine the values at each site and rate the risk of fire in each area from 1 to 5 based on wind speed. Use a 1 to indicate low potential for a fire; use 5 to indicate a high potential for fire.

7. Record your fire potential rating for each site based on its wind speed.

8. Add all the ratings for each site to come up with a total for each.

9. Divide each total by six to come up with an average rating of the fire potential at each site.

10. According to your ratings, which of the five sites has the highest risk of fire? Which site has the lowest risk?
